Felix be correctamente! Lots of discussion in that thread, and yes, it's a book, but read it all to get caught up, and then post questions in that thread, eh? We'll be more than happy to help you out!

HINT: Somewhere in that thread you will find something to this affect: "The $36 muffler, or any slip-on for that matter, MOSTLY affects your engine's power band from 9,000rpm's to redline"... There should also be a discussion why this is, and it has directly to do with back pressure.

Cool? :p

also you lose bottom end without a lil back pressure, which is why on my Z they have a valve much like the new vettes, that at low rpms, shuts off the right side muffler and then opens up as you get faster to allow more top end power.
